    kernel: Add kmod-drm-ttm-helper
    
    Add a package for drm_ttm_helper.ko. CONFIG_DRM_TTM_HELPER is compiled
    into the kernel on armvirt/64, x86/64, x86/generic and x86/legacy
    because also some DRM drivers are compiled into the kernel. On x86/geode
    it is not compiled into the kernel, but kmod-drm-amdgpu and
    kmod-drm-radeon depend on it.
    
    This fixes the x86/geode build.
